The Compression struct in BackendTrafficPolicy lacks the required Kubernetes merge annotations (patchMergeKey and patchStrategy), causing StrategicMerge to fail when merging gateway and route-level compression policies.

Note that this does not solve the issue discussed in #6143 and #6775

can we add another route under Gateway-1 which doesnt have mergeType set, so its compression value would be set to Gzip ?

Sure, added a few more cases in the StrategicMerge test yaml file.
